Figure 12 is the schematic flow sheet of communication server management communication group in the embodiment of the present invention.
In step 1201, the communication server obtains the situation of k-path partition from city map, is every roadRoad pre-sets one or more communication groups.In one example, the covering radius of above-mentioned multiple communication groupsIdentically or comparably, such as each communication group can cover 1 kilometer on this road of region.
In step 1202, the communication server is spaced the first transport information of collection to schedule, according to thisThe communication group that first transport information is adjusted on this road is set.
First transport information refers to the information related to the traffic conditions on this road.Show at oneIn example, first transport information can be：Road k-path partition, travel direction, traffic index, terminal connectConnect number, path coordinate etc..In one example, the communication group sets and included：The number of communication group,Coverage of each communication group etc..
In one example, the method that the communication server adjustment communication group is set is as follows.In current roadWhen the vehicle that road is in congestion, unit path area is more, the communication server exceedes actual number of membersThe communication group of first preset value is split as multiple communication groups, sets the longitude and latitude scope of above-mentioned multiple communication groups,And the Member Users of these communication groups are reallocated.Unobstructed, unit road surface is travelled in present roadWhen vehicle in product is less, the communication server is merged to multiple communication groups of present road so that closedAnd after the actual number of members of communication group be not less than the second preset value, it is ensured that communication group is all the time in enlivening shapeState.In one example, the first preset value and the second preset value are respectively upper limit threshold and lower threshold.
In one example, the method for the number of the communication server adjustment communication group is as follows.Assuming that roadThe length of road 1 in a first direction is L meters, and the terminal connection number of road 1 in a first direction is N, theThree preset values are X.Work as N<It is that road 1 creates 1 communication group during X.Work as N>During X, road 1On the number S of communication group determined according to formula S=N/X.In one example, the warp of each communication groupLatitude scope is by the total length L of road 1, the minimum zone R of communication group, traffic index Y, crossing shapeThe parameters such as state (whether having crossing) are determined.
Figure 13 shows for car-mounted terminal in the embodiment of the present invention to the flow of the communication server more new location informationIt is intended to.
In step 1301, after car-mounted terminal and communication server successful connection, the car-mounted terminal is determined certainlyDynamic frequency from body to the communication server more new location information.
In one example, the dynamic frequency can be adjusted according to the second transport information.Described secondTransport information refers to the information related to the traffic conditions of the car-mounted terminal.In one example, this secondTransport information is one or more driving parameters of the vehicle with vehicle-mounted terminal, such as Vehicle Speed,It is presently in position etc..In one example, second transport information is the peripheral path of the car-mounted terminalSituation, such as congestion in road situation, road closed state, crossing distance etc..
In one example, minimum frequency (minF) and peak frequency (maxF), unit can be setFor millisecond.Assuming that Vehicle Speed is S meter per seconds, " crossing distance " is D meters.In one example,The establishing method of dynamic frequency is as described below.If (D/S)<60, then dynamic frequency is minF.If(D/S)>60 and (F* (D/S)/60)>MaxF, then dynamic frequency is maxF.In other cases, dynamicFrequency is (F* (D/S)/60).Wherein, F is the default frequency pre-set.
As can be seen that being used in the example of above-mentioned setting dynamic frequency to " crossing distance " and " vehicle traveling speedThe two parameters of degree ".In actual applications, can also with reference to be presently in position, congestion in road situation,Other second transport information such as road closed state set dynamic frequency.
In step 1302, the car-mounted terminal determined by dynamic frequency to the communication server more new positionInformation.
It may be noted that car-mounted terminal with dynamic frequency to the communication server more new location information, can for shouldCar-mounted terminal saves the resource such as electricity and flow.In one example, positional information refers to be used to identify thisThe information in geographical position residing for car-mounted terminal, can be the gps coordinate or longitude and latitude of the car-mounted terminalDeng.
In step 1303, the communication server receives the positional information of the car-mounted terminal every time, will basisPositional information after renewal redistributes communication group for the car-mounted terminal.
In one example, when the displacement of car-mounted terminal is larger, beyond the covering of present communications groupDuring scope, the communication server can by the car-mounted terminal from present communications group move to the second communication group.SpecificallyGround, the communication server deletes the mark of the car-mounted terminal and address etc. from present communications group, and will be upperState information and add the second communication group.In one example, deletion and addition of above-mentioned information about firms etc. are operatedIt is transparent for car-mounted terminal, namely car-mounted terminal is not aware that itself is moved to separately from a communication groupOne communication group.In one example, this migration situation can also be informed car-mounted terminal by the communication server,The such as communication server sends communication group migration message to car-mounted terminal, and provides and working as the car-mounted terminalThe final opportunity of preceding communication group speech so that the car-mounted terminal can be using the final opportunity in present communicationsMass-send the valuable chat content of cloth, such as remind present communications group other users in front of exist congestion orThe path problems such as roadblock.

When vehicle 1 continue move ahead, when driving to the longitude and latitude scope belonging to communication group A5, communication serviceDevice automatically exits car-mounted terminal 1 from communication group A6, while car-mounted terminal 1 is added into communication group A5.
Traffic faults are found after viaduct 1406 when vehicle 1 continues to drive to along No. 1 tunnel 1401, then toTurn left into No. 2 tunnels 1402 from east to west in west.Now, the communication server automatically adds car-mounted terminal 1Enter in communication group C1, and car-mounted terminal 1 is exited from communication group A5.Now, the communication server canTo send communication group migration message to car-mounted terminal 1, such as go out on the interface of " vehicle-mounted chat application "Now this communication group migration message, and show " finally propagandaing directed to communicate " button.User 1 presses this and " finally cried outWords " button can send last call instruction, so that last time issues chat content to communication group A5.Now, user 1 can inform that event occurs in the other users road ahead in communication group A5 using the chanceBarrier, lane-change moves back group to vehicle 1, reminds the rear user of vehicle 1 to take measures in time.Or,Receive after the last call instruction, the communication server automatically generates " failure prompting " and is published to communication groupIn A5, it is somebody's turn to do " failure prompting " and is different from the chat content of the proactive dissemination of user 1.It may be noted that sameThere can be multiple car-mounted terminals on vehicle (such as bus etc.) while accessing " vehicle-mounted chat application ",Now each Member Users in communication group refer to a car-mounted terminal.
The traffic that the embodiment of the present invention collects a large amount of car-mounted terminals on road by the special communication server is believedBreath, takes this to set multiple communication groups and above-mentioned communication group is adjusted.Receiving certain car-mounted terminalWhen communication group adds request, appropriate communication group is specified for it according to the positional information of the car-mounted terminal, andIts communication group is changed according to the real-time change of the transport information of the car-mounted terminal.
In one example, itself residing communication group whether change for the car-mounted terminal user andSpeech is transparent, namely the user and is unaware of itself and is switched to another communication group from a communication group.In one example, when car-mounted terminal is exited from a communication group, into after another communication group, communication serviceDevice can also send prompting to the car-mounted terminal so that the user of the car-mounted terminal has last chanceUseful information is issued in the communication group exited.
As can be seen that the embodiment of the present invention can be road driving during user (such as driver orPassenger etc.) provide and interconnected with nearby users, road information situations such as () such as blocking up, repair the roads is shared,Carry out the chance of chat communication.In one example, the embodiments of the invention provide a voice-enabled chat systemSystem, on the premise of driving safety is ensured, various means of communication is provided for vehicle user.Such as,User can be propagandaed directed to communicate using the voice chatting system with the front vehicles of same travel direction, obtain front roadRoad situation.And for example, in case of emergency, kept away by voice chatting system request front, front vehicleAllow, so as to quickly through the section.For another example, it is logical using the voice chatting system before driving doublingKnow the front vehicle of doubling, it is to avoid the situation of " road anger " occurs.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all at thisWithin the spirit and principle of invention, any modification, equivalent substitution and improvements done etc. should be included inWithin the scope of protection of the invention.
